RMI-LUG.

Specification of Letters Patent.

Application filed April 5,

`class adapted primarily for securing` a demountable rim to avehicle'wheel and the .prime feature of the invention is the provi slonof a two part lug structure so arranged that one part may be adjustedwith respect to the other part so that it may be entered between thefelly and rim of the wheel any desired distance.l

A further feature of the invention is the provision of means for holdingthe two parts of the lug structure in adjusted rela-l tion with eachother when the lug structure is applied to use', said adjustments to bemade from time to time as the parts with which the lug structurecooperates become worn'and thus eliminating any squeaky or rattlingnoises. -I

A. further feature of the invention is in so constructing the two `partsof the lug structure that one part may be moved laterally with respectto the other part, Abut will l be held against longitudinal movementin-` dependently of each other.

' Other objects and advantages will be hereinafter more fully set forthand pointed out in the accompanying specification.

In the accompanying drawings which are made a part of this application,

Figure l isv an elevation of a portion of a Wheel structure with a lugattached thereto.

F ig. 2 is an enlarged transverse central sectional view through the lugand the parts to' which it is attached. i

Fig. is a perspective view of the upper portion of the lug structure.

Fig. 4 is a perspective View of the lower portion of the lug structure.

Referring to the drawings, l indicates a wheel felly, 2 indicates arimof the demountable type and 3 indicates a tire, all of which parts maybe of the usual or any preferred type. ln attaching demountable rims towheels of this class lugs are 'ernployed, but after the wheel has beenused for some time, the parts thereof engaged by the lugs become worn tosuch an extent as Paten-ted Jan. it, '1921. ieee. serial no. 371,563.

to cause the wheel to give off a squealring nolse as well as permittingmovement of theI tire and rim independently of the felly of the wheel.

To overcome these objectionable features,

vthe lug structure herein shown is formed in two parts, a lug proper eand a wedge plate 5, the plate 5 entering between'the felly l and therim 2 while the lug 4 is secured to the felly by a bolt 6.

The upper end'of the lug 4.- is provided vwith a laterally extendingfiange 7 upon which 'rests the upder face of the'plate 5, the lug e:having an upwardly and transversely extendingrib 8, the upper facevofwhich is stepped to form shoulders 9 which .engage opposed shoulders l()on the plate 5,

the under face of the plate having a transverse recess 11 in which theshoulders l0 are located, the side walls of the recess 1l engaging theside walls of the rib and holding said plate against longitudinalmovement with respect to the lug. A y

As the parts of the lug structure .become loosened by wear ,orotherwise, the plate is moved inwardly on the lug` 4 one or more notchesand the lug again tightened against the face of the felly, thus movingthe plate further inwardly between the rim and felly than previously,and as the plate is somewhat tapered, this extra inward movementcompensates for any wear or expansion of the parts ofthe wheel andmaintains the rim taut around the felly.

This operation may be repeated from time to time thus guart'ling againstany squeaking or rattling noises belng made as frequently occurs withthense of the ordinary lug, from the fact that when the ordinary lug` isforced against the face of the telly, there is n0 means for furthertightening the wheel run.

It will further be seen that by entering the rib 8 inthe recess il, theplate 5 will be heldy against longitudinal movement. above the lug 4,consequently the plate will not become lost should the lug becomeslightly loosened from the felly.

In operation, the wedge plate 5 is properly positioned above the lug 4and the lug then tightened against the face of the -telly l. Should thewedge become loose by wear or expansion of the rim, the lug 4 is tobeslightly loosened and the wedge moved inwardly a suflicient distancethat when the llO lug is again tightened, the Wedge Will rinly engagethe rim and take up such wear or proper, a wedge plate vseparate fromthelug,

the under` face of said plate having a recess, shoulders in said recessfthe under face of said plate on opposite sides of said recess beingsmooth7 a rib on said lug adapted to enter said recess7 and shoulders onsaid rib adapted to engage the shoulders in the recess and hold theplate in various adjusted positions, the upper face of said lug onopposite sides of said ribs being` smooth for receiving the smooth underiace .of said plate.

2. The combination With a Wheel fellyv` and a rim surrounding and spacedfrom the"A telly, of a lug construction for holding the rim in spacedrelation to the felly comprising a lug, means for clamping the lugagainst the felly, an upwardly and trans- 4versely extending rib at themedial line of the upper face of the lug, stepped shoulders on the upperface of said rib7 a wedge plate adapted to enter between the telly andrim, said plate having a transversely1 extending recess in its underface at its longitudinal center for the reception of said rib, and meanson the meeting faces of said rib and recess for adjusting'said platelaterally of the lug for causing the plate to enter hetween the fellyand rim varying distances.
